我有一个带文本的工作列表视图，现在想用 AQuery 添加图像。
我已经更改了 XML 并添加了 ImageView 元素，现在想通过 AQuery 添加加载图像直到现在我为 TextViews 使用了 SpecialAdapter，但我正在努力获取图像我必须做的事情
到目前为止我的代码，我想我现在必须对适配器做一些事情，比如
aq.id(R.id.imageView).image(c.getString("URL"), false, false);
，但究竟是什么？

更新：抱歉，没有意识到关于我当前的 SpecialAdapter 的问题，我想我必须在那里管理使用 AQuery 下载的图像。但是有人可以帮我吗？
